File Encryption
File encryption is the science of writing the contents of a file in a secret code. For this assignment you will design a
The program should open the file and read its contents, one string at a time. As the program reads a string from the file, it substitutes each character of the string for an alternate character. It then writes the encoded string out to a second file. When the program is finished, the second file will be a version of the first file, but written in a secret code.

CIT244 Program Project 3 Assignment
As with any assigned program, do not wait until the last minute to start. Start early in the week
the program is due so you can ask questions if you get stuck
Node.js and Express and Nunjucks Templates
We have gotten to the good stuff. There is a program similar to this assignment
given as the last example in the lecture notes for the week that discusses node
static files. This program will take more time that previous assignments.
There are several examples you should study first, particularly the pizza order
example program available in the examples programs folder for the week
discussing static files. You should study and run the pizza order program before
trying this program.

Then it would mean that all problems in NP can also be solved in cubic time. If a problem can be solved using Dynamic Programming, then it is not NP-complete. Suppose X and Y are two NP-complete problems. Then, there must be a polynomial-time reduction from X to Y and also one from Y to X.arrow_forwardMaximum Independent Set problem is known to be NP-Complete.
